Best continuous ink system for the Epson R1900

Just purchased my 1st pigment based printer, the Epson R1900. Been involved in all types of photography for about 50 years both professionally as well as for pleasure.
I have owned the stylus 1270, R320 R340 and presently usin the stylus 1400.

I obviously need to cut my printing costs with this new printer and I'm looking at going with a CIS. Preferably with reliable auto reset carts. Just having a hard time coming up with the best choice for a system.
